Hi, and thank you for help in advance

I am a semi-newbie, and just installed Fedora Linux Core 2 on my intel workstation. I can send/receive email, ssh to other machines, but cannot connect to this machine from outside using ssh. When I try ssh, after a while, it gives the following message:

ssh: connect to host XXX.XXX.XXX.XXX port 22: Connection timed out

I tried to disable firewall or set eth0 (intel 82545GM gigabit) as a trusted device, but non of these worked. In my firewall configuration, I even tried allowing incoming telnet , but telnet didn't work either.

After each update of firewall configurations, I ran '/etc/init.d/iptables restart' to make sure
the change is in effect. I have no entry in /etc/hosts.allow or hosts.deny.

The outside machines that I tried to connect without success had: Redhat Linux 9, SGI Irix (can't recall the version), WinXP. At this point, the problem doesn't seem to be a firewall issue. Can it be related to the gigabit network card? I am lost. Can anyone give help please?

Thanks!

Is SSH deamon running?

# service sshd start

Can you even ping the linux box from the outside? If not, then you're probably not on the same subnet.

I checked that sshd is running:

# ps -A |grep sshd
6593 ? 00:00:00 sshd

Also, I already tried ping from outside, and the machine responds OK. Once again, I have no problem sending and receiving emails.

Thanks,

Where are you connecting outside from? Your outside network maybe preventing traffic from port 22 to your network (highly unlikely). Some companies use proxy servers to allow access to the Internet. Maybe you need to add proxy info so that it can forward that request off? Just a thought...

I have checked with the system administrator of the domain, and indeed the SSH port was not open - the problem was not on this Fedora box. Now things work fine. Thank you!
